When he first settled in Napa Valley, Louis M. Martini sought to source from the most coveted vineyards in the region. With the 1938 purchase of the Goldstein Ranch in the Mayacamas Mountains, he embarked on a new chapter in advanced viticulture and vineyard-driven winemaking. The vineyard, renamed Monte Rosso for its red volcanic soils, has since become the emblematic source of some of our most sought-after releases. Today, we continue to source the best grapes possible from Napa Valley and beyond.
